MySQL does not natively support the recursive keyword in common table expressions (CTEs) like some other databases do. However, you can achieve similar functionality using stored procedures or functions in MySQL.
Here's an example of how you can implement recursive functionality in MySQL using a stored procedure:
```sql
DELIMITER //
CREATE PROCEDURE RecursiveProcedure(IN initial_value INT)
BEGIN
-- Base case
IF initial_value > 10 THEN
-- Recursive termination condition
SELECT 'Reached maximum value' AS Result;
ELSE
-- Recursive step
SELECT initial_value AS Result;
CALL RecursiveProcedure(initial_value + 1);
END IF;
END //
DELIMITER ;
-- Call the procedure to start the recursion
CALL RecursiveProcedure(1);
```
In this example, the stored procedure `RecursiveProcedure` takes an initial value as input. It checks if the value has reached the maximum condition (in this case, 10) and terminates the recursion. Otherwise, it outputs the current value and calls itself with the next incremented value.
Please note that this is just a simple demonstration of recursive functionality in MySQL using stored procedures. You can customize the logic inside the stored procedure to fit your specific requirements.
